Bitcoin (BTC) is the original cryptocurrency, often called "digital gold." It's designed as a decentralized store of value with a fixed supply cap of 21 million coins. Right now, BTC trades around $66,000–$67,000 per coin, with a massive market capitalization of about $1.33 trillion. This makes it the undisputed king of crypto, holding roughly 58% dominance in the total market.
Its price is highly volatile — swings of 5–10% (or more) in a single day or week are normal. In 2026 so far, we've seen range-bound trading with occasional sharp pullbacks (like the recent February dip), driven by institutional flows, macroeconomic factors, and the ongoing post-halving cycle. People hold BTC for long-term appreciation, hedging against inflation, or as a speculative bet on adoption growth. Companies are increasingly adding it to their balance sheets, treating it like a treasury asset.
USDT (Tether), on the other hand, is the leading stablecoin, pegged 1:1 to the US dollar. Its price stays extremely close to $1.00 (usually $0.999–$1.001), with almost zero volatility by design. The current market cap sits around $184 billion, making it the third-largest crypto overall and by far the biggest stablecoin.
USDT's purpose is stability and utility. Traders use it as a "safe haven" inside exchanges to park funds during market dips without converting back to fiat. It's the go-to bridge for payments, remittances, DeFi lending, cross-border transfers, and avoiding crypto price swings. Behind the scenes, Tether backs each USDT with reserves (heavily in US Treasuries and cash equivalents), and regulatory clarity in places like the US has boosted confidence in stablecoins this year.
